MEANS Eon PE EnEAT'ING VOLATILE FUEL.

Specification of Letters Patent.

ratented AprQlS,

Application filed September '5, 1919. Serial No. 321,887.

This invention relates to means and method for preheating fuel. gases for'use in internal combustion 7 engines, and. particularly for so preheating the gases by contact with the heated body of the explosion chamber, and so utilizing the heat created by the explosions, to preheat the gases which are successively used to create the explosions, before such gases enter the explosion chamber.

The purposes of the invention are to provide means for so preheating the fuel gases for use-in internal combustion engines, that when such heated gases enter the explosion chamber they will be in a heated and volatile condition and in condition to produce the highest propelling force when exploded-by the ordinary spark supplied; and the further purpose to utilize forsuch'preheating, the

heated part of the explosion chamber.

A further purpose ofmy invention is to provide a chambered cylinder head for the explosion chamber or cylinder, and to pass the gas mixture through the chambers of such head whereby they are properly heated before they enter the cylinder.

My drawings further illustrate my invention, as follows: 7

Figure 1, represents a cross section side view of the device.

Figure 2, represents a sectional plan view, taken on line A. A. on Fig. 1.

Like numerals on the figures represent like parts.

Numeral 1, represents the outer side walls of my heating cylinder head, with a floor 7 supported by and connected upon the top of any ordinary explosion cylinder 20f an internal combustion engine, by means of ordinary bolts and nuts 3, the bolts passing through holes 4 in the side walls of the head 1.

An intake supply pipe 5 brings the supply of gas mixture from any ordinarv carbureter and this is drawn into the chamber 6 of the head by the suction of the piston action in the cylinder 2 as usual. Near one edge of the chamber 6 is placed U shaped baffle wall 9, the points thereof 9 and 9? turned toward 'the outer walls 1 of the head, with spaces between thesaid points and the walll suflicient for the gases to pass between and enter the cylinder 2 through valve 10 and port 10 in lower shell 7 of the head, the valve being provided with a stem 11 and spring 12' with stop cap 13 above the top 8 of the head.

In the said lower shell 7 isalso provided stem 16, which control spring and cap 17 an exhaust port, 1 1 forthe escape'of'the burned gases through a stop valve 15 with and 16, the valve being operated by an ordinary lever 18 on post 19 and connecting rod 20 from the ordinary cam shaft connected to the moving parts of the engine as in ordinary gas engines, the waste matter passing wall in the chamber 6 and adjoining pipe 22. In operation the chambered head 1 is cylinder 2, and thereafter as the gas mixture 'out through connecting part 21 forming a heated by the first explosions of gas in the v is drawn into the chamberG it is heated and expanded in the hot chamber, and brought into a condition to produce a much greater force when exploded than under the usual manner ofbeing introduced cold, andtheengine equipped with'this apparatus will run with less fuel and produce more power.

While I have described the objects and construction of this apparatus'as for gases, yet I do not limit the use and claims and objects thereby, as the apparatus is of equal value in the use of low grade oils and liquid fuels, and by the use of the apparatus I am able to utilize such other liquidfuels by engines equipped with my apparatus, and get results as good as from the use of more expensive fluids and gases when used on an engine without my apparatus, as by my preheating system the low grade liquids are made gaseous and combustible in an explosive cylinder.

I claim:

1. The combination in an internal co1nbustion engine, of a cylinder, a chambered head therefor provided with fuel inlet and exhaust valves in its inner wall, said head being divided by a single partition into two unequal chambers of the full height of said chambered head, both communicating with the combustion space of the cylinder, the larger one by means of the fuel inlet valve and the other by means of the exhaustvalve, said chambers having radial inlet and outlet ports respectively, adjacent each other in the side wall of said head, said inlet port being arranged to direct the incoming fuel obliquely against the partition wall dividing said chambers.

2. The combination in an internal combustion'engine, ofa cylinder, a chambered head thereforprovided with fuel inlet and exhaust valves 1n its inner wall, said head having two chambers, both in communica- ,tion with the combustion space of the cylin- 'baflie plate and the partition separating; said chambers. a V i v v I 7 v 3 The combination in an internal 'combu's tion engine, ofa cylinder, a chambered head therefor, provided with fuel inlet and exhaust valves inits inner wall, said valves being spaced equally from the center of said head on thesame diametrical line, said head having two chambers both communicating with the combustion'space of the cylinder, one by means of the fuel inletvalve and the other by means of theexhaust valve, said chambers having radial inlet and outlet ports, respectively, adjacent each other in the side Wall'of saidhead, a curved partition separating the chambers, said partition partially surrounding the exhaust valve,iand being disposed in the path of the incoming fuel, and a curved baffle wall partially surrounding the fuel inlet valve, there being a narrow space between the battle and the said curved partition, the fuel inlet port being so located as to direct the incoming fuelagainst the partition wall and through the space between said wall and bafile. n

In testimony whereof I ELll lX my signature.
